I am currently using Sketchup to design my new home. The architect did the floor plans, side views, sections etc (with a lot of my input) but I am doing the 3D myself, and also basically most of the interior and landscape design.
I want to make my model accurate and detailed, both interior and exterior. So I am basically adding everything to it, every light fixture, every switch, every outlet, every plant… you get the idea. Also, I want to generate realistic renderings out of it (using Enscape mostly).
Now my problem is that my Sketchup model is nearing 400mb (and that is without the numerous proxies for everything that is more than a few megabytes) and is getting slow. For example I might double click on a component to enter inside it, and then I have to wait several seconds for the component to be opened while I see the Outliner flashing. My PC is a decent desktop with an i7, RTX 2070 and 16GB RAM.
I purge often, I keep certain things (e.g. plants) in separate layers which I turn off when not needed, shadows are off, and I try not to have unnecessarily large textures or too many edges.
Still, textures need to be large enough for the renders to look good. The same with the number of edges, a low poly plant will not look nice when viewed from a relatively close distance. I sometimes download models in FBX and I use transmutr to convert them to enscape proxies, but the skp files generated are many times bigger than the equivalent fbx file, something which slows things down further.
So now I wonder: Have I reached the limits of Sketchup? Is perhaps Sketchup not the right tool for this level of detail and I should now move to something else?
